OTP 24.2
Erlang/OTP 24.2 is the second maintenance patch release for OTP 24, with mostly bug fixes as well as a few improvements.
Below are some highlights of the release:
Highlights
-
crypto: The
cryptoapp in OTP can now be compiled, linked and used with the newOpenSSL 3.0cryptolib. It has not yet been extensively tested, so only recommended for experiments and alpha testing in this release. There are not yet any guaranties that it works, not even together with other. OTP applications like for example SSL and SSH, although there are no known errors. -
erts: An option for enabling dirty scheduler specific allocator instances has been introduced. By default such allocator instances are disabled. For more information see the documentation of the
+Mdaiargument to theerlcommand -
erl_docgen, erts: All predefined types have been added to the
erlangmodule together with documentation. Any reference to a predefined type now links to that documentation so that the user can view it. -
erts: Responsiveness of processes executing on normal or low priority could suffer due to code purging or literal area removal on systems with a huge amount of processes. This since during these operations all processes on the system were scheduled for execution at once. The new solution is to limit the number of outstanding purge and copy requests to 2 times the number of schedulers as default
